Arithmetic status flags are set for this output.Description:When enabled, the MVMT instruction uses a Mask to either pass orblock Source data bits. A “1” in the mask means the data bit is passed.A “0” in the mask means the data bit is blocked.If you mix integer data types, the instruction fills the upper bits of thesmaller integer data types with 0s so that they are the same size as thelargest data type.Enter an Immediate Mask Value Using an Input ReferenceWhen you enter a mask, the programming software defaults todecimal values. If you want to enter a mask using another format,precede the value with the correct prefix.PrefixDescription16# hexadecimalfor example; 16#0F0F8# octalfor example; 8#162# binaryfor example; 2#00110011Arithmetic Status Flags:Fault Conditions:Arithmetic status flags are affected.noneExecution:Condition Function Block Action Structured Text Actionprescan No action taken.
